Answer: (6,2)
Step-by-step explanation:
Replace all occurrences of
y with 2x−10 in each equation.
−x+20=14
y=2x−10
Solve for x in the first equation.
x=6y=2x−10
Replace all occurrences of x with 6 in each equation.
y=2x=6
(6,2)
Point Form:
(6,2)
Equation Form:
x=6,y=2
Answer:
Using substitution method
First make y in equation 1 the subject of formula
Y=4x-2
Sub in equation 2
2(4x-2)-8x=4
8x-4-8=4
8x=4+12
8x=16
X=2
Sub in any of equation to get y
Step-by-step explanation:
Y =4(2)-2=6
Answer:
I think it's C and F. Don't depend on me tho I'm only in the 7th grade but I just told what I think is more logical
Answer:
The answer is 1920, right? Here is how-
The numbers must contain at least three digit and can go above that which means the answer has 3 4 5 and 6 digits all together.
For three digits , there will be 6*5*4 = 120
For 4 Digits, There will be 6*5*4*3=360 possible numbers
For 5 digits , there will be 6*5*4*3*2 = 6! = 720
For 6 digits, there will be 6*5*4*3*2*1 = 6! = 720
<Note- the digits are non repeating as the question said it to be “different digits” >
Now add them up = 120+360+2*720 = 1920
Step-by-step explanation:
Cross multiplication is applied here.
